先说结论：UCAS 没有禁止在个人陈述上用 AI，但它把用法分得很清楚。用来起步、理结构、查可读性，UCAS 自己写了可以；把 AI 生成的文字当成最终文本交上去，UCAS 明确列为不要做的事。提交时你还要声明，陈述不是抄来的、也不是 AI 软件提供的。
UCAS 怎么看「用 AI 写个人陈述」
UCAS 的 AI 指南开门见山回答了「算不算作弊」：
Generating (and then copying, pasting and submitting) all or a large part of your personal statement from an AI tool such as ChatGPT, and presenting it as your own words, could be considered cheating by universities and colleges and could affect your chances of an offer.出处：UCAS：A guide to using AI and ChatGPT with your personal statement
意思是：让 AI 生成全部或大部分内容，再当作自己的话交上去，院校可能认定为作弊，影响你拿录取。紧接着一句说的是申请流程里的声明：
When you complete your application, you now have to declare that your personal statement hasn't been copied or provided from another source, including artificial intelligence software.后果写得也很直白：不是你自己的话，可能被 UCAS 标记为欺诈，拿不到录取或已有录取被撤回。
Anything not in your words could get flagged as fraud by UCAS, and could in turn mean you don't receive any offers or have offers withdrawn.UCAS 写明可以怎么用
同一份指南也说了正确的用法，概括成一句：
there are ways you could use AI to help you make a start, structure, and then check your final work.具体列了三种：
- 找思路：让 AI 列出和专业相关的话题或技能，你再把它们和自己的经历、观点对上。
- 理结构：“You may want to ask ChatGPT to suggest ways of structuring your personal statement answers, ensuring that you're evidencing your skills in a clear way.”
- 查可读性：“ChatGPT can be used to check your personal statement draft for readability.”
指南的「Do / Don't」清单只有两条，值得记住：
- 要做：“Check everything that AI tools suggest, particularly facts.”
- 别做：“Copy and paste from AI tools and use as final text.”
UCAS 还建议去看各院校自己的说法，因为院校可能有单独的 AI 指引：
We'd advise researching what individual universities and colleges recommend you include in your personal statement, and whether they have specific guidance around using AI tools like ChatGPT.相似度检测是怎么回事
所有 UCAS 本科个人陈述都会过相似度检测。按现行的申请人指引，每份陈述会和两个库比对：
Each personal statement is compared against a library of personal statements previously submitted to UCAS, and a library of sample statements collected from websites and other sources.相似度超过 30% 的，由 UCAS 核查团队人工复核，再通知学生和所报院校，怎么处理由院校决定：
Any statements showing a level of similarity of greater than 30% are reviewed by members of the UCAS Verification Team.出处：UCAS：Similarity guidance for applicants。网上还流传一份较早的 PDF 指引写的是「10% 或以上」，它不含 2026 申请季改版说明，本站按含改版说明的现行版引用。
老师帮你查过，也不代表不会被报。UCAS 的 FAQ 专门回答过这个问题：老师给的模板、网上的句子，都可能是被报的原因。
Also, if they gave you a template to use, or you used any sentences from the internet, this may be why your statement has been reported.出处：UCAS FAQ
2026 申请季起的格式
个人陈述从一整篇改成三个问题，每题最少 350 字符，三题合计上限仍是 4,000 字符（含空格）。三个问题是：
- Why do you want to study this course or subject?
- How have your qualifications and studies helped you to prepare for this course or subject?
- What else have you done to prepare outside of education, and why are these experiences useful?

放到文书帮里是什么样
文书帮的 AI 做的是 UCAS 写明可以做的那部分：问你问题、帮你理主线和结构、指出哪段断了。正文由你一段一段自己写，AI 最多给一句示例句，不给整段。每条 AI 回复旁边都标着「AI 生成，仅供参考，强烈不建议直接作为申请材料提交」。
UCAS 的核查口径很简单：
If you provide true, complete and accurate information and if your personal statement is all your own work, then you have nothing to worry about.
